This technology relates to a high-strength electromagnetic shielding carbon nanotube nonwoven fabric using water-soluble highly branched supramolecular linkers and its manufacturing method. Specifically, it is a high-strength EMI shielding CNT nonwoven fabric technology using water-soluble supramolecular linkers.
Existing technologies needed to overcome the limitations of conventional electromagnetic shielding materials, such as high specific gravity, cost, corrosiveness, and low workability, which arose from using nano carbon/polymer composites. To address this, the present technology proposes a configuration that includes a carbon nanotube nonwoven fabric for electromagnetic shielding, manufactured through the π-π bonding of carbon nanotubes and the highly branched structure of polymeric supramolecular linkers.
Accordingly, this technology improves the mechanical strength and thermal properties of CNT nonwoven fabrics, making them suitable for industrialization and environmentally friendly. It has value for use in advanced materials, electronic components, and electronic device fields.
